Last year, Twitter sought to broaden the reach of its software by giving outside developers new tools at its first Flight conference. This year the company will try again, as the pressure on it to grow its user base has only increased.

The event is scheduled to be held on October 21 in San Francisco, Twitter announced Wednesday. An agenda has not yet been released, though attendees can expect new tools for tracking the performance of their apps, and for weaving Twitter content into their apps, which might include Twitter advertising.

Last year, the flagship news at the event was Fabric, a software development kit aimed at helping developers build apps and make money from them. The kit includes tools for crash reporting, embedding Twitter posts, or tracking the effectiveness of ads. There was also a tool released called Digits, which lets users log into apps with a phone number instead of a password.

At Flight 2015, it's possible Twitter could release new tools to let outside developers incorporate some of those new Twitter functions into their own apps. The more Twitter is able to disseminate its features and software into outside apps, the better its ability to expand its user base.
